Delphi/ObjectPascal

Delphi one of the most efficient rapid application development (RAD) environments. It is single executable, easy deployment and distribution as needed. Delphi is a high-level, compiled, strongly typed language that supports structured and object-oriented design. Delphi is based on Object Pascal, thus benefits from object oriented programming, easy-to-read code, quick compilation, and the use of multiple unit files for modular programming. The biggest advantage of Delphi application is its low development and maintenance cost.
